Who Has The Current Lab Answerspaper For Sci 207 Ashford University W

Before you begin this assignment, watch the video titled The Scientific Method Presentation. Then, read “Lab 2: Water Quality and Contamination.” This lab includes investigating the effects of common pollutants on groundwater and simulating the filtration process used by wastewater treatment facilities. You will perform tests on your tap water to compare contaminant levels in bottled versus tap water. Using this information and your eScience lab kit, complete Experiments 1 through 3 on the Week Two Lab Reporting Form.

Ensure that you complete the following tasks before submitting:

• Review the introductory material and watch The Scientific Method Presentation video.
• Perform Experiment 1: Effects of Groundwater Contamination using your eScience lab manual and kit. Complete Table 1 and answer Post Lab Questions 1 through 5 in complete sentences on the Week Two Lab Reporting Form.
• Perform Experiment 2: Water Treatment using your eScience lab manual and kit. Answer Post Lab Questions 1 through 4 in complete sentences on the reporting form.
• Perform Experiment 3: Drinking Water Quality using your eScience lab manual and kit. Complete Tables 2 through 6 and answer Post Lab Questions 1 through 4.
• Complete Experiment 1: Diversity of Plants from Lab 3, Steps 1 through 6, to prepare for Week Three. Results will be submitted next week.
• Submit the completed Week Two Lab Reporting Form via Waypoint. The submission does not require a title page or APA formatting, but any outside resources referenced must follow APA guidelines.

Paper For Above instruction

The science lab assignment for SCI 207 at Ashford University involves a comprehensive exploration of water quality, contamination, and treatment processes, aligned with the scientific method. This laboratory exercise emphasizes understanding how pollutants affect groundwater, evaluating water purification processes, and analyzing drinking water quality, all through hands-on experiments conducted with eScience lab kits, supplemented by critical thinking and analytical questions to deepen comprehension.

The initial phase of this lab requires students to review foundational concepts through a provided video—The Scientific Method Presentation—and then proceed to perform three key experiments: effects of groundwater contamination, water treatment methods, and drinking water analysis. The first experiment involves simulating groundwater pollution, analyzing the adverse effects of contaminants, and recording data in a designated table. Post-lab questions then serve to reinforce understanding of contaminant sources, implications for health and environment, and the scientific principles underlying groundwater contamination.

The second experiment focuses on water treatment technology, where students utilize their kits to replicate filtration processes. Data collected are recorded systematically, and subsequent questions are designed to evaluate the effectiveness of various filtration techniques. This segment highlights the importance of clean water provision and introduces the fundamentals of wastewater treatment systems.

The third experiment pertains to assessing drinking water quality. Students perform tests to measure contaminants such as pH, chlorine, nitrates, and other chemical parameters. The collected data are documented across multiple tables, providing a comprehensive picture of water safety. The post-lab questions aim to interpret the results, understanding the health risks associated with different levels of contaminants, and compare tap water versus bottled water safety.

Furthermore, students are tasked with preparing for the upcoming week’s biodiversity experiment by completing the first six steps of the Plant Diversity experiment, which involves identifying and classifying plant specimens. While the results are to be submitted later, this preliminary work supports understanding of ecological diversity and the biological aspects of environmental science.

This lab assignment not only enhances practical skills in water testing and filtration but also develops critical thinking, data analysis, and scientific reporting skills. The emphasis on APA formatting for external references encourages students to engage with credible sources, reinforcing scientific literacy and research integrity. The overall educational goal is to foster an understanding of environmental processes, human impacts on water resources, and sustainable practices to safeguard water quality.
